Students make their own instruments to measure atmospheric pressure changes.

Now students can learn the basics of barometric pressure, starting with the instrument itself. Using everyday materials such as plastic containers and balloons, students make a simple model that demonstrates how a real barometer registers changes in atmospheric pressure. They then learn how to observe, record, and interpret data as they watch their barometer rise and fall as atmospheric conditions change. The kit includes materials for five barometer models, a teacher’s guide, and a set of copymasters for class activities.
